We recorded our findings, using the Chi Square formula, and filled in the chart, accepting or rejecting out null hypothesis using the degrees of freedom chart. We recorded our results on the white board afterwards to compare with the class

Once we brought the m&ms to our desk, we separated and counted them by colour, recording our results.

We first got approximately 1.5 grams of m&ms in a bowl or plate.

Lab procedures

Then we ate the candy! :)
